A 59-year-old man was admitted to our department with a complaint of upper abdominal discomfort. Endoscopically, there was an irregular ulceration just oral to the major papilla. It caused stenosis of the second portion of the duodenum and prevented the cannulation of the major papilla. The accessory papilla was slightly enlarged, and we could perform ERP through it. There were no abnormalities except for slight dilatation of the main pancreatic duct and the lack of connection between the ventral and dorsal pancreatic ductal systems. US and CT showed cystic dilatation of the Wirsung's duct. Based on these findings, we diagnosed this case as pancreas divisum accompanied by carcinoma of the papilla of Vater Surgical treatment was carried out. Histological study revealed the existence of pancreas divisum accompanied by carcinoma of the papilla of Vater. As far as we could find in the literature, this is only the third reported case in Japan.
